i'm not sure i understand the progressive linkage. how does it work? linkage like on a tunnel ram opens both carbs the same amount @ the same time, wouldn't that increase throttle response? or would it be to much throttle response? i've never used two carbs, thats why i'm asking.

The linkage kit will allow you to run the carbs anyway you want. You can set it to open both carbs at the same time or wait for the first carb to open halfway before opening the second one.

I would set it to open both carbs at the same time. Who cares about fuel mileage....

I figured that I would also need the Linkage kit. Here is the Part:
Progressive Throttle Linkage Kits Part# 7094

Guess I will also need this:

Dual-Quad Fuel Line Kit Part# 8088

What Air Cleaner should I get?

What about painting or cleaning up my other 600 CFM carb?

either is fine

Depends on the motor, if you have something "hotter" the twin 600's would be better but if it is mild vice versa.

I have 2x500's on my F-28 on a moderately worked Ford 5.0. Works great and looks absolutely awesome.

If you have 600's, use'em. The edelbrocks are vacuum secondary carbs so the 200 extra cfm shouldn't kill low end response too bad.

Good luck, and for a car seeing alot of street time the progressive linkage is a must, otherwise you get light switch-like throttle response!

Cheers,
Andy

Either 500s or 600s, the secondaries are not going to open anyway under 6000 rpm

with progressive linkage, you will only run on front 2 bbl of the rear carb most of the time anyhow.

But you will have to tune them for the slow air flow....

Why not 600 cfm?

New RPM Dual Quad Air-Gap Intake

What do you think about the new:

RPM DUAL-QUAD AIR-GAP MANIFOLD
Designed for 1955-86 S/B Chevys, this intake stands 1-5/8" taller than the low-profile C-26 intake and offers performance improvements in the 1500-6500 rpm range. The large runners feature our unique Air-Gap design that separates the runners from the hot engine valley for a cooler, denser charge.
